Discocactus braunii

Discocactus braunii is a small, flattened globular cactus from eastern Brazil, often treated as a form or synonym of another Discocactus, with no wild records under this name in GBIF. Like its relatives it grows in full sun on quartz sand and gravel, and it is notably cold-sensitive for a cactus, so keep it warm even during its dry winter rest.
